Currently, on my save with my hometown club, Scunthorpe Utd we have had back-to-back promotions back into the EFL, reached the FA Cup 5th Round while in the National League & currently sit 22 points clear at the top of League 2.
Also, my son has tested this tactic with 3 teams. Firstly with Brighton, he managed a 3rd place finish & won the Europa League in the first season, a 6th placed finish with Luton Town in the first season & won the EPL & UCL with Man Utd in the first season!!
The tactic can be mirrored too and the left-sided version is included in the zip file.
Also, we did concede A LOT of goals in our first season with Scunny but it was on the Early Access version which did see a ton of goals in the match engine, post patch the tactic is much more solid defensively.
